Virtual GameBoy (VGB) is a program that emulates the Nintendo GameBoy handheld on your computer. It runs GameBoy, Super GameBoy, and GameBoy Color games on PCs, Macs, PocketPCs, Unix boxes, etc. VGB also helps debugging GameBoy software without using a costly development system.
Since its creation, VGB has progressed to support all existing types of GameBoy hardware and cartridges, as well as many add-ons, such as GameLink, Pocket Printer, Rumble Pack, Super GameBoy, etc. It is only legal to play games you actually own with VGB. You will first need to read a game from its cartridge into a file. This can be done with an inexpensive gadget called Bung GB Xchanger or a similar device.
